BIOL 1201 Chapter : Exam 2 (DNA)
Document Summary
**to break the bonds (unzip the dna), the molecules heat up and the bonds can"t hold. To get them to go back together, cool them down slowly** X-ray diffraction of dna: maurice wilkins and rosalind franklin knew that dna formed a helix by the patterns seen in x-ray diffraction. The discovery of dna: wilkins and franklin, watson and crick, pauling. Eukaryotic cell cycle: mitosis, interphase, g1: cell growth and differentiation, s: synthesis of dna; chromosomes are duplicated, g2: cell growth, mitotic cell division, prophase, metaphase, anaphase, telophase and cytophase. The semiconservative replication model: half conserved meaning that half of it is old, half is new. The central dogma of biology: information flow, dna rna proteins, dna rna: transcription, rna protein: translation. Summary: 1) dna structure, 2) replication of dna, semiconservative (half old, half new, dna is where genes are found, and genes encode the information (the blueprints) required to make proteins, mutant and proud!
